As shown in FIG. 1, thepackaging device for panel includes a corner guard 10, a first bufferingbar 21, a second buffering bar 22, and a third buffering bar 23. In thecurrent embodiment, the corner guard 10 is configured with a foldedpackaging material. The substantial folding sequence will be detailedlydisclosed herebelow. Preferably, the packaging material is a paperboard. It can be selected from a cardboard or corrugated board. Incurrent embodiment, the corner guard 10 has triangular shape, while inother embodiment or requirement, the corner guard 10 can be embodied toas square or diamond shape configuration, or other shape. The firstbuffering bar 21, the second buffering bar 22, and the third bufferingbar 23 are attached inside of the corner guard 10. Substantially, thefirst buffering bar 21, the second buffering bar 22, and the thirdbuffering bar 23 are firstly glued to the paper board, and then thepaper board is folded to create the corner guard 10. Alternatively, thepaper board is firstly folded into the corner guard 10, and then thefirst buffering bar 21, the second buffering bar 22, and the thirdbuffering bar 23 are attached thereto. The first buffering bar 21, thesecond buffering bar 22, and the third buffering bar 23 are preferablymade from the same material which can be ethyl vinyl acetate (EVA) orexpandable polyethylene (EPE) or other suitable material.

The packaging device can be used to support and protect the panel.Furthermore, the packaging device can be used on protecting andsupporting any panels from electronics, such as a liquid crystal displaypanel, a glass substrate, and a glass substrate for solar energy, andother displaying panels.

FIG. 2 is a depiction of how the packaging device shown in FIG. 1 isused along with a liquid crystal display panel. As shown in FIG. 2, thepanel 20 to be packed can be a glass substrate, a liquid crystal displaypanel, a glass substrate, and a glass substrate for solar energy, andother displaying panels. The packaging device 30, 31, 32 and 33 areidentical to the corner guard 10 shown in FIG. 1. Each of the packagingdevice 30, 31, 32 and 33 is attached to a corresponding corner of thepanel 20 and the panel 20 is further supported and protected by thefirst buffering bar 21, the second buffering bar 22, and the thirdbuffering bar 23. By this arrangement, the panel 20 is properly andreasonably supported and protected.

FIG. 3 is an unfolded view of the packaging device shown in FIG. 1before it is folded. As shown in FIGS. 1 and 3, the corner guard 10includes a first central portion 11, a pair of second side portions 12,13 and a pair of third end portions 14, 15.

The first central portion 11 includes a pair of first longitudinal sides111, 112 with the second side portions 12, 13 interconnected theretorespectively. The second side portions 12 includes a bottom 121 which isperpendicular to the first longitudinal side 111, and the other secondside portion 13 has a bottom 131 which is perpendicular to thelongitudinal side 112. The second side portions 12, 13 can be folded upas centered on the central portion 11 and arranged in parallel to eachother.

The third end portion 14 are each interconnected to the bottom 121 ofthe side portion 12, and the other end portion 15 is interconnected tothe bottom 131 of the side portion 13. The third end portions 14, 15 canbe folded up with respect to the second side portion 12, 13, and thenoverlapped and glued together.

In the current embodiment, the first central portion 11 and the thirdend portion 14, 15 are rectangular shaped, while the second sideportions 12, 13 have the triangular shape. Of course, they should not belimited to such shapes as those shapes can be readily modified accordingto the field requirements.

FIG. 4 illustrates the corresponding positions of the buffering barsarranged over the corner guard of FIG. 3. As shown, there are the firstbuffering bar 21, the second buffering bar 22, and the third bufferingbar 23, and each of the first buffering bar 21, the second buffering bar22, and the third buffering bar 23 is attached or glued to correspondingportions of the corner guard 10. Substantially, the first buffering bar21 is attached to the first central portion 11; the second buffering bar22 is attached to the end portion 14 of the corner guard 10 so as tosupport one of the two corresponding end surfaces of the panel 20. Thethird buffering bar 23 is attached to the second side portion 13 andcreates a gap with respect to the second side portion 12 such that thecorner of the panel 20 can be inserted into that gap. The thirdbuffering bar 23 is served to support the front or back surface of thepanel 20.

Referring to FIG. 5 which is a partial enlarged view showing encircledportion of A in FIG. 2. As shown in FIG. 5, the panel 20 to be packed isprovided with projection 201 on its frontal or back surface, and abuffering pad 202 is attached onto the projection 201. The buffering pad202 can be glued onto the top of the projection 201 or with othersuitable measurements. By this arrangement, the panel 20 can beprevented from damaging resulted from transversal movement of theprojection 201 from adjacent panel 20.

In the preferred embodiment of the present invention, the projection 201and the third buffering bar 23 are located at the same surface of thepanel 20. In addition, the overall height of the projection 201 and thebuffering pad 202 is smaller than or equal to the height of the thirdbuffering bar 23 and the thickness of the second side portion 13 of thecorner guard 10. By this arrangement, the panel 20 can be effectivelysupported and protected. Furthermore, the overall thickness can also bereduced.

The buffering pad 201, the first buffering bar 21, the second bufferingbar 22, and the third buffering bar 23 are made from same material, suchas ethyl vinyl acetate (EVA) or expandable polyethylene (EPE).

In conclusion, the packaging device effectively embodies as a cornerprotecting device which can effectively provide buffering result to thepanel, while with the minimum packaging material used. With a great dealof packaging material saved, the overall cost is effectively reduced.
